What the evidence actually supports, and why the format keeps spreading

A genre has emerged in which a successful person describes their twelve-step morning routine and the audience is invited to copy it. The interesting question is not whether the protocols work — some do, some don't — but why the format itself has become the thing.

The blue light glasses question, examined

Lab findings, RCT results, and where the popular advice goes wrong

The blue light glasses market is large and growing. The premise — that filtering short-wavelength evening light prevents melatonin suppression and protects sleep — is half-supported by the laboratory research and contradicted by the real-world trials. The science is real. The product is mostly not what the science is about.
